Circumcentre and Orthocentre
Imagine we recieve data from 3 mobile phone masts telling us our suspect is 5 miles from tower A, 4 miles from tower B, 3 miles from Tower C.
We can find the suspect by triangulating his signal. He will be in the circumcentre of the triangle the phone towers make, and the orthocenter of the triangle between the phone towers (This might be useful, as if we only had information from 2 phone towers, we could station someone where they meet as a starting point).
